Karasuba

Cheerful and sociable with a devil may care attitude towards the dangerous situation that they found themselves in, Karasuba might seem like he's fooling around with the way he casually teases everyone (often with a mean edge to it) and shamelessly flirts with Beniyuri but he actually sharper and more perceptive than he appears. Despite the flippant way he carries himself, he's the type who keeps his true intentions to himself and is pretty pragmatic and pessimistic. That said, he makes it pretty clear earlier on that he doesn't really trust anyone in their group.
